The error message indicates that autossh tries to parse the '-e' option
to perl.

Thus, another solution is that parallel tells ssh to stop parsing
options with '--':
ssh localhost -- perl -e \'"print 1"\'

This might even be preferable, given that parallel allows to exchange
the ssh program. I don't know whether all ssh implementations that
parallel wants to support out-of-the-box understand '--', nor do I know
autossh.
